The idea of Snapped's general concept getting revisited does intrigue me, especially after reading this Iwata Asks interview, with some insight about how much the game needed to be dumbed down, thanks to the DSI's horrible camera (thanks to Glowsquid, for telling me about it btw) : http://iwataasks.nintendo.com/interviews/#/ds/dsi/4/0
Personally I never had any issues with Snapped's controls, however I don't know how much that relates to me only ever playing the game on a 3DS, so for all I know the 3DS might be a good fit for a sequel or the Wii U, because from what I have noticed the camera on the gamepad is actually pretty good and the larger screen could also be beneficial, for this kind of game.
